Specification of Letters Patent.

Patented Aug. '7, 1906.

Application filed June 3,1905. Serial No. 263,587.

To all whom it may concern:

Be it known that I, WASHINGTON LAY- oooK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Printing- Stamps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in printing-stamps of that class provided with individual types, usually made of rubber, which are separately set into type-receiving slots of a suitable holder, and refers more speciiically to improvements designed to afford adjustability with respect to the width of the type-receiving slots and the distance apart of said slots and provide for type of different widths and to also provide for variable spacing of the lines of type of the same or different sizes.

The construction herein shown is embraced within the scope of the invention claimed in my prior United States Letters Patent, No. 796,131, granted August 1, 1905, the present improvements relating more specifically to the manner of mounting the type-bars, between which are formed the type-receiving slots, and to the means for maintaining the adjusted position of the bars to provide typereceiving slots of varying width and varying distances between the set-up lines of type in the holder.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a side view, partially broken away, of a hand-stamp embodying my improvements. Fig. 2 is a longitudinal section thereof. Fig. 3 is a transverse section thereof. Fig. 4 is a bottom plan view of the stamp, showing the manner of arranging the type therein. Fig. 5 is a de tail sectional view taken on line 5 5 of Fig. 1.

As shown in the drawings, A designates the body or back of the stamp, herein shown as having the form of a hand-stamp provided with a handle A. Fitted to said body is a type-holding frame, herein shown as made rectangular and comprising side members B B and end members B. The side and end margins of the body of the stamp are rabbeted to receive the said side and end members of the type-holder frame. C C designate bars supported in said frame and between which are formed longitudinal type-receiving slots 0, that receive the types D. The said bars hold the types from lateral movement and act as guides to permit the type to separately I yield rearwardly in the manner hereinafter described. The said bars C are mounted in the frame by being provided with hookedends 0 c which hook over and are thereby connected with transverse bars B B one at each end of the type-holding frame. Said bars B B are so mounted that the distance between the same maybe increased or 'de creased, whereby may be effected a clamping action on the hooked ends of the t pe-bars in such manner as to frictionally liold them from lateral movement and maintain the width of the type-receiving slots. Various means may be employed for effecting such clamping action of the bars B B with the type-bars. As herein shown, the bar B extends transversely between and is permanently fixed at its ends to the side members B B of the type-holding frame, while the bar B is fixed to an extension-frame B slidable on the main frame. Said extension-frame comprises a bar parallel with and located outside of the end member B of the main frame adjacent to the movable clamping-bar B It is provided with arms I) b, which are located outside of the holder frame B of the type-frame, and the end of the movable clamping-bar B extends outwardly through elongated slots 12 in the side members B and are affixed to said arms I) of said extension-frame. E E, extending through and having screwthreaded engagement with said extensionframe and bearing at their inner ends against the adjacent end member of the type-holding frame, act when turned inwardly to separate the clamping-bars and produce the frictional engagement between the same and the hooked ends of the type-bars to hold the type-bars from lateral movement. The types D, which are confined in said type-holding slots, are of that character as shown in my aforesaid application, they being provided at therear of the type-bars with outwardly-facing shoulside members of the type- Clamping-screws ders which bear against the type-bars. The said shouldered parts of the type are confined between said type-bars and a suitable cushion F, which is fixed to the lower side of the back or body A of the stamp. In this manner the type are held from movement longitudinally of the type-slots. The typebars do not engage with a clamping pressure, the narrow ends of the types extending between the same; but said bars are so adjusted that the type yield rearwardly into the cushion when a stamp, the types at this time having guiding engagement with the bars. When said printing pressure is released, the types are forced forwardly into their printing positions by the action of the yielding cushion. During the printing operation of the stamp the body or back moves toward the type-bars, so that while permitting yielding of the type backwardly into said cushion at the same time causes the cushion to be advanced toward the "type, and thus afford a proper backing to produce a uniform impression of the types, notwithstanding irregularity of the surface printed upon or irregularity in the lengths of the types.

Any suitable means may be employed for clamping the type-holder frame to the body of the stamp. As herein shown, said typeholder frame is provided at its ends withbails F, which swing over the ends of the back or body of the stamp when the latter is fitted to the frame. The said bails are made of such length that when swung upwardly into their holding positions clamp the stamp body or back to the frame in a manner to exert a pressure of the yielding cushion against the backs of the types, for the purpose hereinbefore described. It will be observed that when the holding or confining bails are thrown downwardly the back or body of the stamp and the cushion attached thereto may be readily removed from the frame, so as to permit access to the rear of the type-holding slots for removing and setting the types therein. The removal ofthe types is eflected after the clamping mechanism for the bars has been released, so as to permit the bars to be slightly separated.

It is obvious that my invention may be embodied in other forms of construction than that shown without departing from the spirit and scope of the invention, and I do not wish to be limited to the structural details except as hereinafter made the subject of specific claims.

I claim as my invention 1. In a printing-stamp, a type-holder frame, including a plurality of bars between which are formed type-receiving slots, clamping-bars in said frame with which the typebars have interlocking connection, by means permitting movement of the type-bars toward and from each other, and means for spreading apart the clamping-bars to effect endwise clamping action on the type-bars.

2. In a printing-stamp, a type-holding frame, including a plurality of bars between which are formed type-receiving slots, clamping-bars in said frame which are movable toward and from each other, hooks on the type bars which hook over said clamping-bars and means for adjusting the clamping-bars toward and from each other. printing pressure isapplied to the 3.
